Yah. I'm thinking I could dump the image file on the BOSS so it would
be included in the full backups.

| Yes, for everything except bare-metal restore of windows.

| Or, put a firewire card in the machine and get external firewire

| I'm not far enough along to have all the details but far enough

| - Create a Raid 1 mirror partition where you install all of
| backuppc. Do this even if you start with a single drive.
| - Periodically shut down backuppc, unmount the partition,
| break the mirror, swap drives, and resync the raid to
| the new drive.
| I've set up one 250 gig IDE internally and will probably use
| 3 external firewire drives for the rotation. (One off-site,
| one running mirror, one in transit). It takes 7 or 8
| hours for a new drive to sync (but would be less for smaller
| drives). This should work for IDE trays too, but I'd plan on
| rebooting for the swap. I'll probably set up another
| machine so it will be easy to grab older files from the
| drive(s) not currently in use. I may even try just
| breaking the raid without unmounting, since the filesystem
| journal should fix things anyway like it would if you
| lost power at that point.
|
Ok. I'm looking at the raid options now.
And digesting all this info.
Thanks.
